Cementing Techniques for Hip Resurfacing Arthroplasty: An In Vitro Study

In 2 recent retrieval studies, overpenetration of cement, incomplete seating of the prosthesis with a resultant polar cement mass, or both, have been associated with femoral failures of current generation resurfacing arthroplasties. It has been frequently stated that hip resurfacing is technique-sensitive, but scientific investigations into cementing techniques are lacking. We have developed a laboratory model to analyze the associated variables.
